Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91170, here are decompositions:
- 7 + 91163 = 91170
- 11 + 91159 = 91170
- 17 + 91153 = 91170
- 19 + 91151 = 91170
- 29 + 91141 = 91170
- 31 + 91139 = 91170
- 41 + 91129 = 91170
- 43 + 91127 = 91170
Showing the first eight; more decompositions exist.
